Remember those documents I referenced upthread?
The one by
Pope St Pius X says the following:
VI. Organ and instruments
- Although the music proper to the Church is purely vocal music, music with the accompaniment of the organ is also permitted. In some special cases, within due limits and with proper safeguards, other instruments may be allowed, but never without the special permission of the Ordinary, according to prescriptions of the Caeremoniale Episcoporum.
- As the singing should always have the principal place, the organ or other instruments should merely sustain and never oppress it.
- It is not permitted to have the chant preceded by long preludes or to interrupt it with intermezzo pieces.
18. The sound of the organ as an accompaniment to the chant in preludes, interludes, and the like must be not only governed by the special nature of the instrument, but must participate in all the qualities proper to sacred music as above enumerated.
19. The employment of the piano is forbidden in church, as is also that of noisy or frivolous instruments such as drums, cymbals, bells and the like.
- It is strictly forbidden to have bands play in church, and only in special cases with the consent of the Ordinary will it be permissible to admit wind instruments, limited in number, judiciously used, and proportioned to the size of the place provided the composition and accompaniment be written in grave and suitable style, and conform in all respects to that proper to the organ.
Code:
21. In processions outside the church the Ordinary may give permission for a band, provided no profane pieces be executed. It would be desirable in such cases that the band confine itself to accompanying some spiritual canticle sung in Latin or in the vernacular by the singers and the pious associations which take part in the procession.
Sacrosanctum Concilium, on the other hand, said this:
120. In the Latin Church the pipe organ is to be held in high esteem, for it is the traditional musical instrument which adds a wonderful splendor to the Church’s ceremonies and powerfully lifts up man’s mind to God and to higher things.
But other instruments also may be admitted for use in divine worship, with the knowledge and consent of the competent territorial authority, as laid down in Art. 22, 52, 37, and 40. This may be done, however, only on condition that the instruments are suitable, or can be made suitable, for sacred use, accord with the dignity of the temple, and truly contribute to the edification of the faithful.
Pope Bl. John Paul II’s chirograph, also referenced above, said this:
- Again at the practical level, the Motu Proprio whose centenary it is also deals with the question of the musical instruments to be used in the Latin Liturgy. Among these, it recognizes without hesitation the prevalence of the pipe organ and establishes appropriate norms for its use[42]. The Second Vatican Council fully accepted my holy Predecessor’s approach, decreeing: “The pipe organ is to be held in high esteem in the Latin Church, for it is the traditional musical instrument, the sound of which can add a wonderful splendour to the Church’s ceremonies and powerfully lifts up people’s minds to God and to higher things”[43].
Nonetheless, it should be noted that contemporary compositions often use a diversity of musical forms that have a certain dignity of their own. To the extent that they are helpful to the prayer of the Church they can prove a precious enrichment. Care must be taken, however, to ensure that instruments are suitable for sacred use, that they are fitting for the dignity of the Church and can accompany the singing of the faithful and serve to edify them.
That’s why I commended them to you…there is a whole lot of teaching crammed into those three documents.
